1-1Chapter 1IntroductionThe 9F206-02 (as shown in Figure 1-1) is an FDDI repeater module for theMMAC-Plus that provides external access to the Flexible Network Bus (FNB)backplane via two sets of FDDI-compliant A/B ports. This allows the FNB totraverse multiple MMAC-Plus systems, or connect to any ASNI FDDI-compliantdevice in an FDDI network. The 9F206-02 module attaches to both FDDI networkson the FNB backplane, FNB-1 and FNB-2, but can be controlled separately withDIP switches or local management tools. The 9F206-02 can also be used toDual-Home an MMAC-Plus chassis to multiple points in the network. Usingstandard FDDI chip-set technology, the 9F206-02 module completely re-times andregenerates data signals for error free transmission and guaranteedinteroperability.FeaturesSystem ManagementThe 9F206-02 requires minimal management. It can be completely managed andcontrolled through the SMB-1. The management features include the following:• Front Panel Port Status• Insertion/bypass Control (FDDI-1 and FDDI-2) and Status• FPIM Identification (Front Panel)ConnectivityThe 9F206-02 uses FDDI Port Interface Modules (FPIMs) to provide several mediaoptions for the front panel (FNB-1 and FNB-2) interfaces. These FPIMs areavailable in various media types including the following:• Multimode Fiber Optic (FDDI MIC)• Single Mode Fiber Optic (FDDI MIC)• Unshielded Twisted Pair (RJ-45)• Shielded Twisted Pair (RJ-45)• Multimode Fiber Optic (SC)• Singlemode Fiber Optic (SC)
